Creating a Custom Route Table

Scenarios

Constraints

By default, the quota for custom route tables is 0. To create custom route tables, apply for a quota increase first.

Step 1: Create a Custom Route Table and Associate Subnets with It

1. Go to the route table list page.
2. In the upper right corner, click Create Route Table. On the displayed page, configure parameters as prompted.

   Table 1 Parameter descriptions

   Parameter	Description	Example Value
   Name	(Mandatory) The name of the route table. The name: Can contain 1 to 64 characters. Can contain letters, digits, underscores (_), hyphens (-), and periods (.).	rtb-001
   VPC	(Mandatory) The VPC that the route table is used to control traffic routing. The route table can be associated with the subnets in this VPC.	vpc-001
   Description	(Optional) Supplementary information about the route table. The description can contain a maximum of 255 characters and cannot contain angle brackets (< or >).	-
   Route Settings	(Optional) The route information. You can add a route when creating the route table or after the route table is created. For details, see Adding Routes to a Route Table. You can click to add more routes.	-

3. Click OK.

   A message is displayed. You can determine whether to associate the route table with subnets immediately. If you want to associate immediately, perform the following operations:

   1. Click Associate Subnet. The Associated Subnets page is displayed.
   2. Click Associate Subnet and select the target subnets to be associated.
   3. Click OK.

Step 2: Add Routes to the Custom Route Table

Each route table comes with default routes to allow instances in a subnet to access public services on the cloud or to allow different subnets in a VPC to communicate with each other. You can also add custom routes as required to control the traffic in and out of the subnets. For details, see Adding Routes to a Route Table.
